Ni3Al-Ni3V 준이원계 합금 포함 삼원계 시스템에서의 meso-scale 미세구조의 전산 모사에 관한 연구

Abstract

The meso-scale microstructure of the Ni-Ni3Al-Ni3V system is crucial to obtain both high strength and high toughness. Its evolution may be predicted with the aid of computer simulation of the compositional separation for heat-treated alloys. In this study, computer simulations of the hypothetical A-B-C ternary system, which is similar to the system in terms of phase equilibria, have been performed using the kinetic modeling. Simulated morphologies were changed with nominal compositions and model parameters. It was showed the current model was useful and the more realistic model was proposed.
